    Sammanfattning : This thesis gives different views on the modeling and simulation of physical systems, especially together with embedded systems, forming mechatronic systems. The main considered application domain is automotive. LÄS MER

  3. 12. CONCRETE FORM[ing]WORK : Design, Fabrication, Simulation and Correlation of Parametrically Patterned Flexible Formwork and Concrete

    Författare :Annie Locke Scherer; Oliver Tessmann; Jonas Runberger; Remo Pedreschi; KTH; []
    Nyckelord :HUMANIORA; HUMANITIES; concrete; flexible formwork; geometry; parametric patterning; craft; smocking; simulation; correlation; betong; flexibel formsättning; geometri; parametrisk mönsterkonstruktion; hantverk; smockning; simulering; korrelation; Architectural Technology; Arkitekturteknik;

    Sammanfattning : Concrete is one of the most commonly used construction materials, yet industrial fabrication continues to default to established standards of planar formwork and uniform cross-sections for the sake of simplicity and predictability. The research conducted within Concrete Form[ing]work explored alternative methods of producing concrete formwork with a simple, technical re-imagination of material: exchanging the familiar, i.

  4. 13. Prediction of springback in sheet metal forming: with emphasis on material modeling

    Författare :Per-Anders Eggertsen; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Springback; Hardening law; Elastic degradation; Yield surface; Simulation; Bauschinger effect;

    Sammanfattning : The prediction of springback is probably the area in sheet metal forming simulation, where the least success has been achieved in terms solution accuracy. The springback is caused by the release of the residual stresses in the work piece after the forming stage. LÄS MER

  5. 14. A Novel Fiber Interaction Method for Simulation of Early Paper Forming

    Författare :Gustav Kettil; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fiber suspension flow model; object-object interaction model; contact forces; lay down simulations; paper forming; immersed boundary methods; contact forces;

    Sammanfattning : In the forming section of a paper machine, a fiber suspension is flowing down onto a forming fabric, and a paper structure is formed. By using computer simulations this process can be studied, attaining new knowledge helping to improve paper quality and machine efficiency. LÄS MER

  7. 15. Experimental and computational investigation of the roll forming process

    Författare :Michael Lindgren; Högskolan Dalarna; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rollforming; Roll Forming; Flexible roll forming; Rullformning; Simulering och experimentell undersökning av rullformningsprocessen;

    Sammanfattning : One of the first questions to consider when designing a new roll forming line is the number of forming steps required to produce a profile. The number depends on material properties, the cross-section geometry and tolerance requirements, but the tool designer also wants to minimize the number of forming steps in order to reduce the investment costs for the customer.
